- If you're best suited for the question according to your description: ANSWER
- If another agent is better according its description: CALL '%s' function with their agent name
When transferring: OUTPUT ONLY THE FUNCTION CALL`

- 如果根据你的职责描述,你最适合回答这个问题:ANSWER
- 如果根据其职责描述,另一个 agent 更适合:调用 %s 函数,并传入该 agent 的名称
